Melvin Seaboalt, Colville, Washington
This filter was purchased for a Kubota B7500 tractor. It was too long to fit into the filter housing without damaging the cover. I called K&N and was told that they would review the product as for the Kubota tractor. I received a refund with no hassle. I have used other K&N filters and the all very good products.
